The results showed that the varieties and activity of POD isoenzyme expression exist in difference in anther of male sterility line and maintainer in different development stage in sweet pepper and hot pepper. POD isozyme activity of anther was very low in meiosis stage in male sterility line of sweet pepper. There is a POD special band in meiosis and pollen mature stage in male sterility line of pepper respectively.

Indica variety ZYQ8 is an important genetic resource resistant to rice blast disease in rice breeding in North China.in this study,resistance identification of the populations of F1,F2,DH and B1F1of the crosses of ZYQ8×Jingxi17 (JX17) and ZYQ8×Lijiangxintuanheigu was carried out by using a Chinese differential strainZH10-8-14 from North China and a Japanese differential strain Ken54-04 from Japan and the results demonstrated that ZYQ8 had one dominant major gene Pi-zh which had been reported by Zhu L.H., et al., The results from experiments in which the F2 populations of ZYQ8×nine different varieties with known resistant genes were inoculated with strain Ken54-04 indicated that the gene Pi-zh was a new gene and non-allelic to nine known gene loci,namely Pi-i,Pi-km,Pi-z,Pi-ta,Pi-ta2,Pi-zt,Pi-kp,Pi-b and Pi-t.

籼稻品种窄叶青8号是我国北方稻区水稻育种上重要的稻瘟病抗源之一。本文利用我国北方稻区的代表菌系中10-8-14和日本的代表菌系研54-04，对窄叶青8号与感病品种京系17号和丽江新团黑谷的杂交F1、F2、DH和B1F1群体进行抗病性鉴定。根据抗病性的分离，确认窄叶青8号的抗性由1对显性主效基因，即朱立煌等报道的Pi-zh基因控制。利用菌系研54-04接种窄叶青8号与9个具有已知抗病基因的鉴别品种杂交的F2群体，各群体都表现二基因的独立遗传，证明Pi-zh基因与Pi-i、Pi-km|、Pi-z、Pi-ta、Pi-taz、Pi-zt、Pi-kp、Pi-b和Pi-t等9个已知抗病基因间存在非等位关系，是新的抗稻瘟病基因。
